Synthesis and characterisation of N,N-disubstituted 2-amino-5-acylthiophenes and 2-amino-5-acylthiazoles
摘要:
Starting from halomethyl-ketones 8 and N,N'-persubstituted thioacrylamides 7 or their 2-aza analogues 11 a series of N,N-disubstituted 2-amino-5-acylthiophenes 10 and 2-amino-5-acylthiazoles 12, respectively are available. By starting from 1,3-dichloroacetone and using the same thioacrylamide derivatives 7 and 11 N,N-disubstituted 2-amino-5-(chloroacetyl)thiophenes 13 and 2-amino-5-(chloroacetyl)thiazoles 14 as well as N,N'-persubstituted bis-(2-amino-5-thienyl)ketones 15, 2-amino-5-thienyl-(2-amino-5-thiazolyl)ketones 16, and bis-(2-amino-5-thiazolyl)ketones 17, respectively are available.

A series of thiophene derivatives which are substituted in the 2 -position by a morphoIin-4-yl substituent, and in the 3 -position by a substituted ethynyl moiety, being selective inhibitors of PI3 kinase enzymes, are accordingly of benefit in medicine, for example in the treatment of inflammatory, autoimmune, cardiovascular, neurodegenerative, metabolic, oncological, nociceptive or ophthalmic conditions.
The Interplay of Thio(seleno)amide/Vinylogous Thio(seleno)amide “Resonance” and the Anisotropic Effect of Thiocarbonyl and Selenocarbonyl Functional Groups
spectra assigned. Both the NMR data and the results of theoretical calculations at the abinitio level of theory were employed to elucidate the adopted structures of the compounds in terms of E/Z isomerism and s-cis/s-trans configuration. In the case of the asymmetrically N(Me)Ph-substituted compounds, abinitio GIAO-calculated ringcurrent effects of the N-phenyl group were applied to successfully determine

substitution pattern at C(5), with aryldiazonium salts 1 either at their C(3) or C(5) position yielding the corresponding 3-arylazo-2-morpholinothiophenes 9 or, under elimination of the substituent at C(5), 5-arylazo-2-morpholinothiophenes 10. This reaction contrasts to the behaviour of 5-morpholinothiazoles 8 and dimethylaniline 13 towards the same diazonium salts 1 which are unable to couple with these compounds
Deep purple: By the transformation of readily available N,N-disubstituted 2-aminothiophenes and 2-aminothiazoles into heterocyclic analogues of Crystal Violet, such as, tris(2-dimethylamino-5-thienyl)methinium prechlorate (cation shown), the series of dyes derived from these heterocyclic structural units as the important chromophoric component is significantly extended and a gap in the class of heteroanalogous triphenylmethane dyes has been closed.

In the reaction of N,N-disubstituted 3-amino-3-chloropropenylidenedimethyliminium salts 2 with sodium sulfide or sodium selenide, a simple route for preparing N,N-disubstituted 3-aminothioacryldimethylamides 3 and N,N-disubstituted 3-aminoselenoacryldimethylamides 4, respectively, was elaborated.
